Investors, at least, seem quite happy with the focus on technological innovation, as Walmart’s shares jumped to an all time high last month after third quarter earnings were published last month.

Of course, the past year has been kind to Amazon and the corporate world in general, so it’s difficult to say whether Walmart’s happy returns are the result of its investments in cutting-edge technology. Many of the moves are, after all, meant to pay dividends down the road, rather than in the short term. The raft of whizz-bang announcements certainly attracted its fair share of headlines, though—so in 2018, it’ll be interesting to see if the company for which the term “big box store” was basically invented has truly pulled off a technological transformation.
